Meanwhile, if a remote controller operation with respect to the display apparatus 100 is performed in accordance with execution of a remote application, the control unit 270 may control to execute other applications being executed previously in a background mode. For example, if a remote controller operation with respect to the display apparatus 100 is performed as a remote application is executed while a game application is being executed, the game application is executed in a background mode and may return to a previous state if the execution of the remote application is completed.

The user terminal apparatus 200 may include an exclusive button unit (not shown) indicating that a remote controller function is being executed. In some cases, the exclusive button unit (not shown) may function as a mode conversion button unit serving as a remote controller.

FIG. 13 is a flowchart to explain a method for providing a UI of a user terminal apparatus according to an exemplary embodiment.

According to the method for providing a UI of a user terminal apparatus illustrated in FIG. 13, UI information data regarding a user interface screen corresponding to at least one application displayed on an external apparatus is received in communication with the external apparatus (S1310).

Subsequently, the received UI information data is converted using a predetermined UI information conversion format (S1320).

Subsequently, a user interface screen corresponding to the converted UI information data is displayed on a screen (S1330).

In addition, if a user command is input, a remote controller application may be executed in accordance with the input user command, a connectable external apparatus may be searched, and an icon corresponding to at least one searched external apparatus may be displayed.

UI information data may be received from an external apparatus corresponding to a selected icon from among icons corresponding to the external apparatus

If there is a predetermined event or a user command, UI information data corresponding to the predetermined event may be converted using a predetermined UI information conversion format and transmitted to an external apparatus.

If there is a movement of a user terminal apparatus after a predetermined event occurs, an operation state of an external apparatus may be controlled according to the degree of the sensed movement.

In this case, a display screen may be embodied as a touch screen, and the predetermined event may be a touch event by a user.

In the exemplary embodiment, a computer-readable-recording-medium including a program for executing the above-described method for controlling a display apparatus and a method for providing a UI of a user terminal apparatus may be included. The recording medium readable by a computer includes all kinds of recording media where data readable by a computer system is stored. The recording medium readable by a computer includes ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage apparatus, and etc. Meanwhile, the recording medium readable by a computer may be distributed in a computer system connected via a network, and may store and execute a code readable by a computer using a distribution method.

According to the exemplary embodiment described above, an application may be easily manipulated and a content navigation may be easily performed in a display apparatus though a remote controller function.

Although a few exemplary embodiments have been shown and described, it would be appreciated by those skilled in the art that changes may be made to the exemplary embodiments without departing from the principles and spirit of the inventive concept, the scope of which is defined in the claims and their equivalents.
